Pressure Canner with jsars and tomatoes on side

Be prepared for canning season by having everything ready to preserve those delicious foods you either grow or buy during this time of the year. The first step to take is making sure your pressure canner is working properly. The dial gauge of your pressure canner should be checked for accuracy and overall condition every year before you begin preserving foods for the season.

Why Testing Your Canner’s Gauge?

Regular handling, constant use, age, and storage conditions of your pressure canner can affect the accuracy of the gauge and eventually the safety of the foods you want to preserve.

Research-tested recipes for pressure canned foods are based on specific temperatures and times that aim to kill harmful bacteria and/or control its growth. If the pressure is lower than that recommended for processing, the internal temperature of the food will not be high enough to kill all the pathogens that can produce harmful toxins and cause illness, long term health issues or death.

On the other hand, if a dial gauge is inaccurate and the processing temperature is higher than recommended, the food inside the jar may be overcooked affecting the quality of it.

Brands that can be tested:

  • Presto
  • Maid of Honor
  • National
  • Magic Seal

Other brands cannot be tested since we do not have specific information on the gauges and their calibration. Please contact the manufacturing company for assistance with other brands not included here.

When and Where are We Testing?

This year we will be having free dial gauge testing at two locations:
